(a) Among nine randomly selected goblets, how likely is it that only one is a second? Recall that the formula for calculating binomial pmf probabilities is: b(x; n, p) = where x represents the number of successes (S), n represents the number of trials, and p represents the probability of success, P(S). Also recall that (:). ni C Tn- x)lx A company that produces fine crystal knows from experience that 18% of its goblets have cosmetic flaws and must be classified as "seconds." Nine goblets are randomly selected and we are asked to find the probability that only one goblet is a "second." Thus, and x Therefore, in this situation, we have: b
